20 ADDISONIA 
Vegas, nor Brother Leon, of the Colegio de la Salle in Havana, 
have ever seen the plant growing wild in Cuba, nor has it been seen 
outside of gardens during any of our Cuban expeditions. Its col- 
lection by Dr. Rose in a wild state at the locality mentioned in 
Mexico seems to prove that that country is its home. 
This cactus grows readily and flowers freely under dry green- 
house conditions, and its rose-pink flowers are attractive, but its 
barbed bristles are quite the reverse. In addition to the plant 
which furnishes our illustration, our collections contain others 
obtained from M. Simon, of St. Ouen, Paris, and a fine plant pre- 
sented by Mr. John S. Holbrook. 
The genus Nopalea consists of about seven recognized species, all, 
so far as known, natives of Mexico and Central America. The 
generic name is from Nopal, the Mexican name of the cochineal 
cactus, Nopalea cochenillifera, which is also applied to other species 
and to some prickly pears of the genus Opuntia. Nopalea differs 
from Opuntia in having the petals appressed to the stamens and 
shorter than them; in Opuntia, the petals spread away from the 
stamens, and exceed them in length. 
In so far as our examination of literature has gone, we have found 
no previous illustration of this species. Its fruit is undescribed, 
and none of our plants have, as yet, produced mature fruit.
